Plesk 12.x / Linux :: Can't Change SSL Certs For IP Addresses

I have installed a new SSL cert and tried to assign it to an IP address.

Plesk says "Information: The properties of the IP address .... were changed."

But it seems the SSL cert was not changed.

Running in mysql the following query

select d.name from domains d inner join hosting h on h.dom_id = d.id where h.certificate_id = <id of new cert>;
gives:

Empty set (0.00 sec)

I changed the cert for the IP where all my domains are so it should show the domains using that IP/cert. Running the query using the ID of the old cert lists all the domains on that IP/cert.
